Prophylls are the first leaves formed in the axillary shoot. A pair of opposite leaves are usually formed in dicots, while a single leaf in monocots. Morphological diversity of prophylls are explained by fusion or reduction. A prophyll of Cercidiphyllum japonicum <\/i>has two main veins, suggesting the single prophyll is formed by a fusion of two prophylls (Kumazawa 1979). Another possibility is the fusion of two stipules of a subtending leaf (Dr. Jin Murata, personal communication) .<\/p>\n

Both long and short shoots of Cercidiphyllum japonicum<\/i> are sympodial and a shoot of a next year is formed at the leaf axils of the previous year. A prophyll, two scale leaves, and a normal leaf are alternately formed in two rows in both types of shoots. In a long shoot, a lateral shoot meristem covered with stipules of the first normal leaf oppositely form subsequent normal leaves. The switch of alternate phyllotaxis to opposite one is special in Cercidiphyllum <\/i>and some other angiosperms (Kumazawa 1979).<\/p>\n

The lateral shoot meristem of a short shoot has two fates. One is to be arrested and the other to form the inflorescence. However, the long shoot meristem is destroyed, lateral shoot meristems of short shoots change their fate to form a long shoot. The difference between long and short shoots should be regulated by auxin (Titman and Wetmore 1955). Similar auxin involvement between long and short shoot development is found in Ginkgo biloba \uff08Gunckel and Wetmore 1946a, b, Gunckel and Thiman 1949, Gunckel et al. 1949). The same number of leaves are formed in a short shoot as that in a long shoot in Ginkgo biloba. Only one leaf is formed in Cercidiphyllum japonicum<\/em>.<\/p>\n
